Yes, I compile the libraries like this (straight from the Makefile):
OPTIONS=-c -g -Wall -march=pentium-m -msse3 -pipe
LDFLAGS=-g -lX11 -lGL -lGLU
#Skipped the objects here...
PyModules: LDFLAGS+=-shared -lboost_python -lpython2.4
all: $(OBJS) PyModules
%.o : %.cpp Makefile
$(GCC) $(CFLAGS) $< -o
$(GCC) $(OBJS) $(LDFLAGS) -o $(OUTPUT)
So each source file is compiled like this:
g++ -c -g -Wall -march=pentium-m -msse3 -pipe -I../../Source/Include
../../Source/Implementation/PythonModules/CoreModule.cpp -o CoreModule.o
And then linked like this:
g++ CoreModule.o -g -lX11 -lGL -lGLU -shared -lboost_python -lpython2.4
-shared -lboost_python -lpython2.4 -o ../../Game/Core.so
But when I try to import the module into Python (import Core) i get the
Traceback (most recent call last):
File "./foo.py", line 3, in ?
ImportError: /home/ext/workspace/06proj/Game/Core.so: undefined symbol:
So I have to link with AutoreleasePool.o
After I have linked with all objects that is required and creates
another module and imports it AFTER the core module I still get the same
error for the new module. The only way to get it working is to link with
those modules again but that creates to separate modules. For instance,
I have an event dispatcher in the core module. Another module I try to
create also needs the event dispatcher but since the is linked
separately into both modules they cannot communicate.
I don't want to have everything in a big module, I want to split things
up. I can live with a core module that have all code with circular
dependencies etc but I don't want everything in it.
Doesn't it compile the shared libraries as it should? Since they don't
seem to behave like one. I only have experience with creating shared
libraries in c/c++ for use with c/c++ but as I understood it was
basically the same?
